The object of my present invention has been to produce a novel form ofadjustable window Screen.

A primary feature of my` invention resides in the special constructionof frame for the screen whereby I am enabled to employ a screen memberor screen members of Xed Width notwithstanding that my screen isadjustable to occupy windows of different Widths in order that it may tthe particular window upon which it will be finally disposed for use.The reason that I am enabled to utilize screen members of uniform orpredetermined width is due to the fact that in the construction of myscreen unit I avail of adjustment of relatively wide side frame membersin order to obtain the variable widths for my screen thatwill permit ofits application or fitting to diiferent Widths of windows. The sideframe members are assembled in a somewhat unique manner in relation `tothe screen member or members, whereby to be adjusted in respect to thelatter, the side edges of the screen members fitting into the side framemembers of my unit, which frame members may slide relatively to thescreen members for adjustment facility.

My screen unit is also novel in respect to the provision of pluralscreen members if the latter are to be used, there being provided aspecial arrangement of such screen members disposed in vertical linewith one another and adapted to overlap to provide the necessarycontinuous screen surface for my screen, suitable means being suppliedfor obtaining the necessary guiding functions of the screen members onthe frame and relatively to each other when moving the same topredetermined adjustments depending on the vertical height of aparticular window to which the screen is to be fitted.

My invention involves other special features of construction designedfor facilitating the assembly and adjustment of the parts or members ofa screen of the type which I have devised, and which features will befully understood upon reference to the following specification, inconjunction with the accompanying drawings, in

Specically describing myscreen construction, and referring to thedrawings, it is noted that my screen comprises a lower screen memberseen best infFigures 8 and 9, said member comprising the screen body ormaterial I, at the side edges of which are attached by rivets orotherwise the metal strips 2, the said'strlps 2 supporting at theirupper ends the cross bar or strip 3 which reinforces the upper edge ofthe screen member or material I and is also attached to the latter atsaid upper edge. The lower end of the screen member I has affixedthereto a cross or bottom frame member 4, which is of fixed lengthslightly greater than the width of the screen member I, and between thefront and rear sides of which are received the lower ends of the metalstrips 2. The bottom frame member 4 may be made in two sections so as toreceive therebetween the metal strips 2 and the lower end portion of thescreen member or material I, the outer section of the frame member dthus referred to being relatively thin and being designated 4a. Carriedby the lower frame member 4 are the U-shaped guide members 5. Thesection 4a of the member l extends a short distance above the upper edgeof the inner body section of the said frame' member, as seen best inFigure 12.

The foregoingsetsvforth theg'neral construction of the main or lowerscreen member of my screen.

The upper screen member of my screen is designated 6 and is made of theusualscreen material carried primarily by themupper cross frame member'I of my screen, which iframe.member-lis seen best in Figure 8 ascomprising a'f'rlatively heavy and vertically wide dimensioned crossbarr made up of a relatively thick'outer--section'and a.

f Suche lower portions Ia are sufficiently spaced, in Yrespect to thecomplementary side frame memrelatively thin inner section of materialsuch a y wood or other substance from which the'zscreen frame structuresmay be made. The upper edge of the screen member or material E is"received between lthetwo sectionsf'of the rmember 7, `as seen best insectional View Figure 13,"and "attached to the outer section `ofthemember "I and extending downwardly therefrom are flangedside ibars ofmetal designated 9, the same being connected at their lower 'endsbyfthe'fcross barI secured at itsoppo'site ends 'to 'the metal `Ib'ars"9, which latter are formed-with 'gusset sectionsSa at their lower endsto reinforce-the' connection between the parts' B and AW. I Attached t'okthe inner faces of the `angedrnetal bars are strips Elb of Wood orsuitable material, betweenwhich and the bars Il the verticaledge's ofthe screen member or material 6 are clamped'and 'fastened by suitablefastening bra'ds or like fastenings passing through the parts6'-,'f9,and'b.

I pass now t'o the' construction "orf the slide frame members of myscreenfb'oth of which side frame members are made exactly the same sothat they are practicallyinterchangeablein tl'e assembly of the screen.--I'slhall describe, in "ccri'i junction with the disclosure of Figure*10 lof .my drawings', the structure cof each ofthesel side framemembers las follows. Each side fvraiiie member is generally designatedlliz and is made up of an uppersectioII anda lower section IZ."

Y

For connecting the side frame members A with the screen members I and 6,I utilize screw boits passing through openings 24 in the parts 2l andIsa, said screw bolts design-ated 25, and also passing through the slotsI5 of the parts "f" and 4, as previously described. These screw bolts 25cooperate with the slots I5 to limit the lateral or widening extensionof the screen and the narrowing contractionof the screen in thedirection of its width. l

For additionally assisting in holding the main screen member I with itsvertical edges and parts, in the grooves I3, the upper ends ci the lowerside frame sections I2 have at their upper ends U-.shaped corner stopmembers 2S which have cross webs 2do, that constitute stops. Saidstops26a, are engageable with stop lugs 21 which are directly attached togpposite extremities of the part 3. The loops 26a can slide against thelugs El as seen according to the disclosure in Figures 15, i6, and 18,and thus limit the outward movement of the parts I2a at the upper endsof the latter.

For supporting the screen upon a window in which it will be emplaced, Iutilize a supporting plate 28 attached to the outer side of the crossbar 'i after known practice, said plate having a slot to engage with alug carried by a plate 2li attached to the upper cross bar B of theframe of the window which is indicated at C generally.

For quick loosening of the fastening bolts 25, wing nuts 3Q are appliedto said bolts at the inner side of the screen. For interlocking thescreen at its lower end to the window frame, the members Ia areequipped, as seen in Figure 3, with L-shaped clip members 3l adapted tointerengage with the outer window sash stop strips of the window frame.

The method of mounting and the operation of my window screen, accordingto the structure before described, is as follows: It is assumed that thescreen members are assembled substantially in the condition in whichthey are seen in Figure 2. rIhe screen will have the wing nuts 30loosened preliminary to placing the screen in the window frame, and thiswill permit of ready separating or moving together of the side framemembers A, and since the upper sections Il of said side frame membersare loosely slidable in relation to the lower sections I2, the verticalextension of the screen may be readily effected, dependent upon thevertical dimension of the window frame.

The parts being so set and arranged, say as seen in Figure 2, the rststep is to pass the window screen through the window from the inside andinterengage the plates 28 and 29 after the known manner of suspendingand supporting screens as practiced today. The operator will spread theside frame members A if the window is wider than the adjustment of theparts as seen in Figure 2, the latter adjustment being the minimum widthto which the screen parts can be set. This separation will cause thescreen members and frame parts to properly engage the sides of thewindow frame and the vertical dimension of the screen will be arrived atby merely permitting the lower sections of the side frame members A togravitate relatively tothe upper. sections IIuntil-the lower frame bar 6rests upon the usually l outwardly inclined sill of the window frameu`Then the clips or fastening members 3|' can :be interengaged `with thelower ends of thefoutermost stop strips of the frame.v With suchadjustment of the parts, the thumb nuts 3d will .be screwed up tight toholdthe frame members in their proper positions. Of course,` if desired,a suitable fastening device can be employed to attachthe lower frame barto the'window framabut this is not necessary. `'lheooross 'bar or stripIil` ofv the upper screen member 6 and the cross bar or strip 3 of thelower screen member I contacteach with the screen material of theopposing screen member seal the space between the screen members atwhatever vertical adjustments they assume,` preventing entrance of dirtand also insects at such point of contact.

it willi thus be seen that `Ihave devised a screen whichis adjustablein`width toan extent substantially 'equal tothe 'width of the framemembers A, `and is further adjustable in length a distance equivalenttothe combined lengths of the screen members i and 6.' At all lateraladjustments'. of the' members A the vertical cdgesfofthe screen membersI and 6 remain housed or inset within 'themembers A.

It is to be comprehendedrwithin the scope of my invention that screensof xed vertical length may be produced using the general principle ofconstruction employed by me and utilizing only the main screen member I.Under such conditions the secondary screen member 6 could be dispensedwith.

Having thus described my invention, what I claim as new yand desire tosecure by Letters Patent of the United States, is
